Mounting Bonding Techniques Millimeterwave GaAs MMICs
should attached directly ground plane eutectically with conductive epoxy (see general Handling, Mounting, Bonding Note). Microstrip transmission lines 0.127mm mil) thick alumina thin film substrates recommended bringing from chip (Figure 0.254mm mil) thick alumina thin film substrates must used, should raised 0.150mm mils) that surface coplanar with surface substrate. accomplish this attach 0.102mm mil) thick 0.150mm mil) thick molybdenum heat spreader (moly-tab) which then attached ground plane (Figure Microstrip substrates should brought close possible order minimize bond wire length. Typical die-to-substrate spacing 0.076mm 0.152 mils).

Handling Precautions
Follow these precautions avoid permanent damage. Storage: bare placed either Waffle based protective containers, then sealed protective shipment. Once sealed protective been opened, should stored nitrogen environment. Cleanliness: Handle chips clean environment. attempt clean chip using liquid cleaning systems.

Transients: Suppress instrument bias supply transients while bias applied. shielded signal bias cables minimize inductive pick-up.
General Handling: Handle chip along edges with vacuum collet with sharp pair bent tweezers. surface chip fragile bridges should touched with vacuum collet, tweezers, fingers.
Mounting
chip back-metallized mounted with AuSn eutectic preforms with electrically conductive epoxy. mounting surface should clean flat. Eutectic Attach: 80/20 gold preform recommended with work surface temperature tool temperature When 90/10 nitrogen/hydrogen applied, tool temperature should expose chip temperature greater than more than seconds. more than seconds scrubbing should required attachment. Epoxy Attach: Apply minimum amount epoxy mounting surface that thin epoxy fillet observed around perimeter chip once placed into position. Cure epoxy manufacturer's schedule.
Wire Bonding
Ball wedge bond with 0.025mm mil) diameter pure gold wire. Thermosonic wirebonding with nominal stage temperature ball bonding force grams wedge bonding force grams recommended. minimum level ultrasonic energy achieve reliable wirebonds. Wirebonds should started chip terminated package substrate. bonds should short possible <0.31mm mils).
